The magnetic powder clutch is composed of active rotor (input
shaft),driven rotor(output shaft) and yoke with excitation coil.
The three parts are assembled relative concentric and form a system
which can rotate relatively. The annular gap between active rotor
and driven rotor is full of magnetic alloy powder which has high
magnetic conductivity.

The magnetic powder will be in the state of loose situation when
the current do not pass the excitation coil, the magnetic powder
will be thrown on the inner wall of active rotor, in this case,
there will not exist the interaction force between the active and
driven rotor. So the magnetic powder clutch is in the state of
separation, no torque transmission exits.

The magnetic powder in the working chamber will link in a link
state under the action of the magnetic flux generated from the yoke
when the current pass the excitation coil. The magnetic powder
clutch can transfer torque relying on the shear force generated
from magnetic chain and the friction generated from the magnetic
powder and working face. In this situation, the magnetic powder
clutch is in the combination state.

When the current is cut off, the magnetic flux will disappear along
with the disappearance of the magnetizing current, the magnetic
powder will be in the state of loose under the action of gravity
again, and will be thrown on the inner wall of active rotor under
the action of the centrifugal force.In this case, the magnetic powder clutch will be in the state of
separation again.

The magnetic powder clutch and brake have the same principle, the
magnetic powder brake will form as long as driven rotor of the
magnetic powder clutch is fixed.

Remarks:

(1): The formal installation method (high-speed rotating side as
the input side) to use magnetic powder clutch.(2): Please note that the moisture. Magnetic particle moisture, the
performance will become unstable, so be especially careful not to
let the oil or moisture intrusion internal.(3): Please note that the surface temperature.
